APPARATUS FOR DISPENSING AERATED WATERS.

SPECIFICATION forming part of Letters Patent No. 300,288, dated June 10, 1884.

Application filed May 12, 1893.

To a-ZZ whom, it may concern:

Be it known that I, Josnrn HnwEs'SI-inr- HERD, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Dispensing Aerated lVaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to apparatus for dis pensing soda or other aerated waters and it consists in the peculiar construction of the draft-faucet, whereby the aerated water escaping by it is allowed to flow directly in an unbroken or uninterrupted stream into the glass under full pressure, or be broken up or distributed over a large surface and be discharged into the drinking-glass with greatly diminished pressure and enlarged stream. As is well known, in the dispensing of soda or other aerated waters the method pursued is to first discharge into the glass a comparatively small quantity under full pressure to produce the desirec foam, the filling of the glass being subsequently completed under much less pressure. p

I The object of one portion of my presentinvention is to construct a faucet which shall by a simple manipulation be adapted to allow the water to escape from it directly under full pressure, or be diverted and distributed over a comparatively large surface to diminish its pressure; and I carry out this portion of my invention by forming the nozzle of the faucet with a spherical or other enlarged chamber, and placing in this chamber a globular or other shaped gate of less diameter, adapted to turn on its axis to the extent of ninety degrees of a circle, this gate being formed with an axialpassage which shall in one of the two extremes of position of said gate coincide with the outlet of the valve-chamber of the faucet and permit the liquid escaping by such outlet to make exit directly through such passage, while in the other extreme of position of the (No model.)

gate the passage stands at right angles to the said outlet, and the escaping liquid is compelled to .course about the exterior of the gate. My invention relates, secondarily, to means for shutting off access to the faucet of the liquid under pressure when it becomes desirable to remove, inspect, or clean the faucet, this portion of my invention consisting in the combination, with the channel which supplies the liquid to the faucet, of a chamber forming part of such channel and containinga cut-off valve of peculiar construction by which the channel is interrupted or left free, as the case may be, this cut-off valve being hereinafter described.

The drawings accompanying this specification represent in Figure 1 a vertical section,

and in Fig. 2 a horizontal section, of a faucet containing my improvements. Fig. 3 is a sea tional plan of the valve and chamber connected with the supply-pipe of the faucet. Fig. 4: is a plan of the valve which governs the supply of liquid to the faucet. Fig. 5 represents a sectional view of a modification of my invention.

In said drawings, A represents the body of a faucet of ordinary construction in general form, the valve of such faucet being shown at B, its valve-chamber at G, the inlet or supply port of such chamber at D, its outlet or discharge port at E, and its nozzle at F.

In carrying out the main feature of my invention I form the nozzle F with a spherical or other formed chamber, G, and arrange with in this chamber concentrically a globular gate or intercepting device, H, of considerably less diameter than the chamber G, such gate being supported upon the inner end of a horizontal shaft, 1, supported in bearings in a cap, J, which screws into an opening in one side of the nozzle F, said gate H having an axial passage, H, which preferably is of larger diameter than the outlet E of the valve-chamber. The outer end of the shaft I is provided with a lever, L, whereby said shaft is actuated so as to turn said gate to the extent of ninety degrees of acircle, or thereabout. Suitable stops may be provided to prevent said lever and cap from being turned too far in either direction. These are not indispensable, and have not been illustrated in the drawings. When the gate is turned to one of its extremes, as shown in Fig. 1 of the drawings, the passage H of the gate H is in axial alignment with the outlet E of the valve-chamber, and liquid from such chamber escapes under full pressure directly through said passage H Without diversion or interruption. WVhen the gateis turned to its opposite extreme, the solid portion of the gate is presented to the outlet E, and the escaping current is diverted in its course about the exterior of the gate and broken up and distributed through a comparatively extended area with a proportional diminution in pressure. To shut off communication between the valvechamber of the faucet by closing the common supply-port D, before named, I form in the horizontal arm I) of the structure which contains such passage a circular chamber, 0, which intercepts the liquid-supply port D. \Vithin the chamber 0, and closely filling the bottom thereof, I place a flat circular valve, 6, containing in its under side a pocket or valve-chamber, f, having a lateral segmental opening, 9, extending through the periphery of the valve, the substance of the valve being considerably thicker at the ends of this segmental opening than at the side opposite such opening, the two extremes of thickness being shown at h i in Fig. 4 of the drawings. The valve 0 has a handle, j, by which it is actuated, the extremes of movement of this handle and of the valve being determined by a segmental orifice, 70, formed in the wall of the valve-chamber c, as shown in Fig. 8. \Vhen the valve 6 is turned to one of its extremes, the passage D is opened and free communication had with the valve-chamber of the faucet, for the reason that the segmental opening 9 of said valve is opposite the mouth of the passage D, while the mouth of the passage D is always open. In the other extreme of the valve its thick portion h covers the mouth of the passage D and communication with the valve-chamber is cut off. To retain the valve e securely in place and prevent rotation of it, as well as to release it when desired to change it, I screw into the mouth of the pocket or chamber fa plug, 1,

adapted. to be raised and lowered, this construction being shown in Fig. 1 of the drawings.

I have described and shown the gate as a spherical one; but I do not restrict myself to this form, as a flat or irregular plate or block may be employed. I prefer the spherical form, as providing a large surface, and one which distributes the liquid uniformly. A semispherical gate, as shown in Fig. 5 of the drawings, would be an alternative form of the spherical one, with this difference, that when the concavity of the gate was uppermost the liquid would be intercepted in such manner as to be entirely relieved from pressure except that of gravity.

The valve 6 may, if desired, be made to perform a double duty--that is to say, in lieu of being employed simply to shut off flow of liquid to the faucet, it maybe used as a valve to regulate the amount of liquid flowing to or through the faucet.

I claim' 1. The combination, with a faucet, of a ball of less diameter than the water-way, and located in said water-way and having passage through it, substantially as set forth.

2. The combination, with a faucet, of an intercepting device arranged permanently in, the middle of the water-way thereof, said device being of less diameter than the interior of said faucet, and provided with means for turning it so as to allow the water to run freely or to interrupt the flow of water, as may be preferred.

3. In combination, the chamber 0, having a peripheral opening, 76, and valve 6, having pocketf and segmental opening 5 the mouths of the interrupted channel D terminating in the valve-seat and governed by the valve.

In testimony whereof I affix my signature in presence of two witnesses.
